CRJ Electronics CRJ 4-Pin Molex to Dual 15-Pin SATA Power Adapter Cable

Bottom line: The CRJ 4-Pin Molex to Dual 15-Pin SATA Power Adapter Cable: Powers two SATA drives from one spare 4-pin Molex peripheral lead; main trade-off: legacy 4-pin Molex connector is low-tolerance and needs careful pin alignment.

Pros & Cons

Pros

  • ✓ Powers two SATA drives from one spare 4-pin Molex peripheral lead
  • ✓ All-black connectors and dense black sleeving hide the run in a windowed case
  • ✓ 12-inch (30cm) length reaches drive cages without coiling slack
  • ✓ Adds SATA power to older ATX supplies that shipped Molex-only

Cons

  • ✗ Legacy 4-pin Molex connector is low-tolerance and needs careful pin alignment
  • ✗ Only 12 inches (30cm) end to end, tight for top-mounted or far-side drive bays
  • ✗ Two SATA outputs share a single Molex rail, so drive count per lead is capped
  • ✗ Sleeving stiffens the cable and limits tight bends behind the motherboard tray
